Defect in cellular respiration renders sac fungi infertile

The formation of fruiting bodies for sexual reproduction is a central developmental process in fungi. Even though genetic methods have been applied in recent decades to identify a large number of factors involved in this process, we still lack an understanding of how the formation of different cell types is regulated. A research team has gained new insights by studying a mutant sac fungus that is infertile. The mutant is impaired in its respiratory chain, thus lacking the energy to form fruiting bodies.
